Labor unions enthusiastically backed the Obama administration’s health-care overhaul when it was up for debate. Now that the law is rolling out, some are turning sour.

Union leaders say many of the law’s requirements will drive up the costs for their health-care plans and make unionized workers less competitive. Among other things, the law eliminates the caps on medical benefits and prescription drugs used as cost-containment measures in many health-care plans. It also allows children to stay on their parents’ plans until they turn 26.

To offset that, the nation’s largest labor groups want their lower-paid members to be able to get federal insurance subsidies while remaining on their plans. In the law, these subsidies were designed only for low-income workers without employer coverage as a way to help them buy private insurance.

This would be humorous if not for the fact that this law will result in big health insurance/health care cost increases for all Americans.
